The rear surface of the second receiving portion 27B is also a receiving surface that is substantially perpendicular to the front-rear direction. Of the rear end portion of the second locking hole 26B, the space behind the second receiving portion 27B (receiving surface) is open to the rear surface 24R of the rear wall portion 24. The height dimension (vertical dimension) of the area in front of the receiving surface of the second receiving part 27B in the second locking hole 26B is smaller than the thickness dimension (vertical dimension) of the second locking part 17B, and the cylinder The thickness is the same as or slightly smaller than the thickness of the shape accommodating portion 16.

図２に示すように、後壁部２４の後面２４Ｒのうち挿通孔２５の開口領域と、後壁部２４のうち係止孔２６Ａ，２６Ｂの開口領域は、互いに面一状（平坦状）に連なっている。この形態によれば、後壁部２４の後面２４Ｒが広い範囲（ほぼ全領域）に亘ってフラットになるので、形状の簡素化が実現されている。   As shown in FIG. 2, the opening region of the insertion hole 25 in the rear surface 24R of the rear wall portion 24 and the opening region of the locking holes 26A and 26B in the rear wall portion 24 are flush with each other (flat shape). It is lined up. According to this embodiment, the rear surface 24R of the rear wall portion 24 is flat over a wide range (substantially the entire region), and thus simplification of the shape is realized.

図２，３に示すように、後壁部２４には、その後面２４Ｒにおいて左右方向に長いスリット状に開口するとともに、前方へ深く袋小路状に凹まされた形態の二対の操作孔２８Ａ，２８Ｂが形成されている。一対の第１操作孔２８Ａは、一対の第１係止孔２６Ａの上方近傍に配置され、第１係止孔２６Ａと第１操作孔２８Ａとを仕切る第１隔壁２９Ａ（第１受け部２７Ａを含む）は、水平な板状をなしている。第１操作孔２８Ａの後端部と第１係止孔２６Ａの後端部は、第１受け部２７Ａより後方の空間を介して連通している。したがって、後壁部２４の後面２４Ｒにおいては、図３に示すように、第１係止孔２６Ａ（第１受け部２７Ａより後方の空間を含む）と、第１操作孔２８Ａとが互いに連通した状態で開口している。   As shown in FIGS. 2 and 3, the rear wall portion 24 has two pairs of operation holes 28A and 28B that are open in the shape of a slit that is long in the left-right direction on the rear surface 24R and that are deeply recessed forward.

Is in the form of a horizontal plate. The rear end portion of the first operation hole 28A and the rear end portion of the first locking hole 26A communicate with each other through a space behind the first receiving portion 27A. Therefore, on the rear surface 24R of the rear wall portion 24, as shown in FIG. 3, the first locking hole 26A (including the space behind the first receiving portion 27A) and the first operation hole 28A communicate with each other. Open in state.

一対の第２操作孔２８Ｂは、一対の第２係止孔２６Ｂの下方近傍に配置され、第２係止孔２６Ｂと第２操作孔２８Ｂとを仕切る第２隔壁２９Ｂ（第２受け部２７Ｂを含む）は、水平な板状をなしている。第２操作孔２８Ｂの後端部と第２係止孔２６Ｂの後端部は、第２受け部２７Ｂより後方の空間を介して連通している。したがって、後壁部２４の後面２４Ｒにおいては、第２係止孔２６Ｂ（第２受け部２７Ｂより後方の空間を含む）と、第２操作孔２８Ｂとが互いに連通した状態で開口している。   The pair of second operation holes 28B are disposed in the vicinity of the lower portion of the pair of second locking holes 26B, and the second partition wall 29B (the second receiving portion 27B is separated from the second locking hole 26B and the second operation hole 28B). Is in the form of a horizontal plate. The rear end portion of the second operation hole 28B and the rear end portion of the second locking hole 26B communicate with each other via a space behind the second receiving portion 27B. Therefore, on the rear surface 24R of the rear wall portion 24, the second locking hole 26B (including the space behind the second receiving portion 27B) and the second operation hole 28B are opened in a state of communicating with each other.

一括ゴム栓３０の後面３０Ｒの形状は、ハウジング本体１１、筒状収容部１６及び後壁部２４と同じく、略方形をなしている。図２に示すように、一括ゴム栓３０には、複数のキャビティ１２及び複数の挿通孔２５と対応する複数のシール孔３１が、前後方向に貫通して形成されている。各シール孔３１の内周には、周知形態のリップ部が形成されている。また、一括ゴム栓３０の外周にも、周知形態のリップ部が形成されている。一括ゴム栓３０は、後方から筒状収容部１６内に収容するとともに、ハウジング本体１１（インナハウジング１０）の後面１１Ｒを覆うように取り付けられている。一括ゴム栓３０をインナハウジング１０に取り付けた状態では、一括ゴム栓３０の外周のリップ部が、筒状収容部１６のシール面１９に対して液密状に密着する。   The shape of the rear surface 30 </ b> R of the collective rubber plug 30 is substantially rectangular, like the housing body 11, the cylindrical housing portion 16, and the rear wall portion 24. As shown in FIG. 2, a plurality of seal holes 31 corresponding to the plurality of cavities 12 and the plurality of insertion holes 25 are formed in the collective rubber plug 30 so as to penetrate in the front-rear direction. A well-known lip portion is formed on the inner periphery of each seal hole 31. A lip portion having a well-known form is also formed on the outer periphery of the collective rubber plug 30. The collective rubber plug 30 is housed in the cylindrical housing portion 16 from behind and is attached so as to cover the rear surface 11R of the housing body 11 (inner housing 10). In a state where the collective rubber plug 30 is attached to the inner housing 10, the lip portion on the outer periphery of the collective rubber plug 30 is in liquid tight contact with the seal surface 19 of the cylindrical housing portion 16.

アウタハウジング２０とインナハウジング１０は、アウタハウジング２０の筒部２１に対してインナハウジング１０を前方から挿入するようにして組み付けられる。両ハウジング１０，２０を組み付けた状態では、筒部２１の後端部が筒状収容部１６に外嵌されることにより、両ハウジング１０，２０の上下左右方向（両ハウジング１０，２０の組付け方向と交差する方向）への相対変位が規制される。また、筒状収容部１６の後端縁が、後壁部２４の前面に対し前方から当接又は接近して対向することにより、インナハウジング１０がアウタハウジング２０に対して後方への相対変位を規制される。   The outer housing 20 and the inner housing 10 are assembled to the cylindrical portion 21 of the outer housing 20 so that the inner housing 10 is inserted from the front. In the state where both housings 10 and 20 are assembled, the rear end portion of the cylindrical portion 21 is externally fitted to the cylindrical accommodating portion 16, so that both the housings 10 and 20 are vertically and horizontally (assembled of both the housings 10 and 20. Relative displacement in the direction intersecting the direction) is restricted. Further, the rear end edge of the cylindrical housing portion 16 abuts or approaches the front surface of the rear wall portion 24 from the front, so that the inner housing 10 is displaced rearward relative to the outer housing 20. Be regulated.

また、両ハウジング１０，２０を組み付ける過程では、各係止部１７Ａ，１７Ｂが係止孔２６Ａ，２６Ｂに嵌入する。係止部１７Ａ，１７Ｂが係止孔２６Ａ，２６Ｂ内に嵌入する際には、まず、係止部１７Ａ，１７Ｂの楔状をなす後端部が係止孔２６Ａ，２６Ｂ内に進入し、係止部１７Ａ，１７Ｂの進入が進むのに伴い、係止孔２６Ａ，２６Ｂと操作孔２８Ａ，２８Ｂとを仕切る隔壁２９Ａ，２９Ｂが操作孔２８Ａ，２８Ｂ側へ逃げるように弾性撓みする。そして、係止部１７Ａ，１７Ｂが受け部２７Ａ，２７Ｂに係止する正規の組付け位置まで嵌入されると、係止部１７Ａ，１７Ｂが隔壁２９Ａ，２９Ｂを通過するので、隔壁２９Ａ，２９Ｂが係止孔２６Ａ，２６Ｂ側へ弾性復帰し、係止部１７Ａ，１７Ｂの係止面１８Ａ，１８Ｂが係止孔２６Ａ，２６Ｂの受け面に対して後方から係止又は接近して対向する。   Further, in the process of assembling both the housings 10 and 20, the locking portions 17A and 17B are fitted into the locking holes 26A and 26B. When the locking portions 17A and 17B are fitted into the locking holes 26A and 26B, first, the rear end portions of the locking portions 17A and 17B that are wedge-shaped enter into the locking holes 26A and 26B. As the parts 17A and 17B enter, the partition walls 29A and 29B partitioning the locking holes 26A and 26B and the operation holes 28A and 28B are elastically bent so as to escape toward the operation holes 28A and 28B. Then, when the locking portions 17A and 17B are inserted to the proper assembly positions where the locking portions 17A and 17B are locked to the receiving portions 27A and 27B, the locking portions 17A and 17B pass through the partition walls 29A and 29B. The locking holes 26A and 26B are elastically returned to the locking holes 26A and 26B, and the locking surfaces 18A and 18B of the locking portions 17A and 17B are locked or approached to the receiving surfaces of the locking holes 26A and 26B from behind.

この係止部１７Ａ，１７Ｂと係止孔２６Ａ，２６Ｂの係止により、インナハウジング１０がアウタハウジング２０に対して前方（離脱する方向）への相対変位を規制される。また、係止部１７Ａ，１７Ｂの係止対象である受け部２７Ａ，２７Ｂは、係止孔２６Ａ，２６Ｂの内周を段差状に凹ませることによって形成され、係止部１７Ａ，１７Ｂの全体が係止孔２６Ａ，２６Ｂの内部に収容された状態となる。この構成によれば、係止部１７Ａ，１７Ｂの後端部は、後壁部２４の後面２４Ｒから外方（後方）へ突出せずに済む。以上により、両ハウジング１０，２０が組付け状態に保持される。   Due to the locking of the locking portions 17A, 17B and the locking holes 26A, 26B, relative displacement of the inner housing 10 in the forward direction (in the direction of detachment) with respect to the outer housing 20 is restricted. The receiving portions 27A and 27B, which are the locking targets of the locking portions 17A and 17B, are formed by denting the inner periphery of the locking holes 26A and 26B in a stepped shape, and the entire locking portions 17A and 17B are formed. It will be in the state accommodated in the inside of locking hole 26A, 26B. According to this configuration, the rear end portions of the locking portions 17A and 17B do not have to protrude outward (rearward) from the rear surface 24R of the rear wall portion 24. Thus, both housings 10 and 20 are held in the assembled state.

両ハウジング１０，２０が組み付けられると、後壁部２４が一括ゴム栓３０の後面３０Ｒを覆うように位置し、複数の挿通孔２５が複数のシール孔３１と対応するように位置する。そして、端子金具１３から後方へ導出された電線１４がシール孔３１を貫通し、電線１４の外周とシール孔３１の内周との隙間が液密状にシールされる。尚、キャビティ１２に端子金具１３を挿入する際には、端子金具１３が挿通孔２５とシール孔３１を順に貫通する。   When both the housings 10 and 20 are assembled, the rear wall 24 is positioned so as to cover the rear surface 30 </ b> R of the collective rubber plug 30, and the plurality of insertion holes 25 are positioned so as to correspond to the plurality of seal holes 31. And the electric wire 14 led out from the terminal metal fitting 13 penetrates the seal hole 31, and the gap between the outer periphery of the electric wire 14 and the inner periphery of the seal hole 31 is sealed in a liquid-tight manner. When inserting the terminal fitting 13 into the cavity 12, the terminal fitting 13 passes through the insertion hole 25 and the seal hole 31 in order.

両ハウジング１０，２０を組付け状態にロックする係止部１７Ａ，１７Ｂは、後壁部２４の後面２４Ｒに開口する係止孔２６Ａ，２６Ｂ内に収容された状態で、後壁部２４の後方から目視可能とされている。両ハウジング１０，２０が組付け途中の状態では、隔壁２９Ａ，２９Ｂが操作孔２８Ａ，２８Ｂ側へ弾性変位して、隔壁２９Ａ，２９Ｂ（受け部２７Ａ，２７Ｂ）の全厚さ領域が係止部１７Ａ，１７Ｂと並ぶように位置して目視できる。また、両ハウジング１０，２０の組付けが完了した状態では、隔壁２９Ａ，２９Ｂが弾性復帰するので、隔壁２９Ａ，２９Ｂ（受け部２７Ａ，２７Ｂ）の一部が係止部１７Ａ，１７Ｂの陰に隠れて目視できなくなる。したがって、隔壁２９Ａ，２９Ｂと係止部１７Ａ，１７Ｂとの位置関係、及び隔壁２９Ａ，２９Ｂの全体が目視し得るか否かによって、両ハウジング１０，２０の組付け状態（係止部１７Ａ，１７Ｂと係止孔２６Ａ，２６Ｂの係止状態）を検知することができる。   The locking portions 17A and 17B that lock both housings 10 and 20 in the assembled state are accommodated in the locking holes 26A and 26B that open on the rear surface 24R of the rear wall portion 24, and are located behind the rear wall portion 24. It is possible to see from. In a state where both housings 10 and 20 are being assembled, the partition walls 29A and 29B are elastically displaced toward the operation holes 28A and 28B, and the entire thickness region of the partition walls 29A and 29B (receiving portions 27A and 27B) is the locking portion. It can be visually observed by being positioned side by side with 17A and 17B. In addition, when the assembly of both the housings 10 and 20 is completed, the partition walls 29A and 29B are elastically restored, so that a part of the partition walls 29A and 29B (receiving portions 27A and 27B) is behind the locking portions 17A and 17B. Hidden and invisible. Therefore, depending on the positional relationship between the partition walls 29A, 29B and the locking portions 17A, 17B and whether the entire partition walls 29A, 29B are visible, the assembled state of the housings 10, 20 (the locking portions 17A, 17B). And the locking state of the locking holes 26A and 26B).

また、両ハウジング１０，２０を離脱する際には、後方から操作孔２８Ａ，２８Ｂに治具（図示省略）を差し込んで、係止部１７Ａ，１７Ｂと受け部２７Ａ，２７Ｂとの係止を解除する。治具としては、マイナスドライバー又はそれと同じ形状のものを用いることができる。係止を解除するときには、治具の先端を操作孔２８Ａ，２８Ｂの奥端まで差し込み、その治具を、操作孔２８Ａ，２８Ｂの奥端を支点として係止孔２６Ａ，２６Ｂから逃げる方向へ傾ける。すると、治具で押された操作孔２８Ａ，２８Ｂが、係止孔２６Ａ，２６Ｂから逃げる方向へ変位するとともに、隔壁２９Ａ，２９Ｂと受け部２７Ａ，２７Ｂも操作孔２８Ａ，２８Ｂに追従して係止孔２６Ａ，２６Ｂから逃げる方向へ変位する。このように受け部２７Ａ，２７Ｂが変位することにより、受け部２７Ａ，２７Ｂが係止部１７Ａ，１７Ｂから外れて、係止が解除される。本実施形態では、係止部１７Ａ，１７Ｂの係止対象である係止孔２６Ａ，２６Ｂが、後壁部２４の後面２４Ｒに開口しているので、係止部１７Ａ，１７Ｂと係止孔２６Ａ，２６Ｂの係止を解除する際の作業性に優れている。   Further, when both the housings 10 and 20 are detached, a jig (not shown) is inserted into the operation holes 28A and 28B from the rear to release the locking between the locking portions 17A and 17B and the receiving portions 27A and 27B. To do. As the jig, a flat-blade screwdriver or one having the same shape can be used. When releasing the lock, the tip of the jig is inserted to the back end of the operation holes 28A and 28B, and the jig is tilted in a direction to escape from the lock holes 26A and 26B with the back ends of the operation holes 28A and 28B as fulcrums. . Then, the operation holes 28A and 28B pushed by the jig are displaced in the direction of escaping from the locking holes 26A and 26B, and the partition walls 29A and 29B and the receiving portions 27A and 27B follow the operation holes 28A and 28B. It is displaced in a direction to escape from the stop holes 26A, 26B. Thus, when receiving part 27A, 27B displaces, receiving part 27A, 27B remove | deviates from latching | locking part 17A, 17B, and latching is cancelled | released. In the present embodiment, the locking holes 26A and 26B, which are the locking objects of the locking portions 17A and 17B, are open on the rear surface 24R of the rear wall portion 24. Therefore, the locking portions 17A and 17B and the locking holes 26A are provided. , 26B is excellent in workability when releasing the lock.

また、後壁部２４の後面２４Ｒの形状とインナハウジング１０の後面１１Ｒの形状が、略方形をなしており、係止孔２６Ａ，２６Ｂが、後壁部２４の外周を構成する４辺のうち互いに略平行な上辺２４Ａと下辺２４Ｂに沿って、夫々、一対ずつ設けられ、上辺２４Ａに沿った一対の第１係止孔２６Ａの間隔と、下辺２４Ｂに沿った一対の第２係止孔２６Ｂの間隔とが異なった寸法とされている。この構成によれば、アウタハウジング２０とインナハウジング１０を不正に反転した向きで組付けようとしても、係止部１７Ａ，１７Ｂと係止孔２６Ａ，２６Ｂが整合せずに係止できないため、不正な向きでの組付けを防止することができる。   Further, the shape of the rear surface 24R of the rear wall portion 24 and the shape of the rear surface 11R of the inner housing 10 form a substantially square shape, and the locking holes 26A and 26B are among the four sides constituting the outer periphery of the rear wall portion 24.
